The results presented in this article show that the use of the next-generation Chroma-Chem® 897 waterborne no-VOC colorants can help paint formulators comply with current and developing VOC coating requirements.
With the amendment of the Clean Air Act in the early 1970s, it was recognized that VOC emissions from paint may accelerate the process by which sunlight and nitrogen oxides generate ozone, which is the major component of smog. Therefore, efforts to regulate VOC emissions in the United States were initiated. The regulations vary depending on the region or state in the United States; however, the most stringent limits were developed in California for architectural and industrial maintenance coatings (AIM).
